## Abstract
<details><summary>Click Here</summary>
High-quality instruction data is critical for aligning large language models (LLMs). Although some models, such as Llama-3-Instruct, have open weights, their alignment data remain private, which hinders the democratization of AI. High human labor costs and a limited, predefined scope for prompting prevent existing open-source data creation methods from scaling effectively, potentially limiting the diversity and quality of public alignment datasets. Is it possible to synthesize high-quality instruction data at scale by extracting it directly from an aligned LLM? We present a self-synthesis method for generating large-scale alignment data named Magpie. Our key observation is that aligned LLMs like Llama-3-Instruct can generate a user query when we input only the left-side templates up to the position reserved for user messages, thanks to their auto-regressive nature. We use this method to prompt Llama-3-Instruct and generate 4 million instructions along with their corresponding responses. We perform a comprehensive analysis of the extracted data and select 300K high-quality instances. To compare Magpie data with other public instruction datasets, we fine-tune Llama-3-8B-Base with each dataset and evaluate the performance of the fine-tuned models. Our results indicate that in some tasks, models fine-tuned with Magpie perform comparably to the official Llama-3-8B-Instruct, despite the latter being enhanced with 10 million data points through supervised fine-tuning (SFT) and subsequent feedback learning. We also show that using Magpie solely for SFT can surpass the performance of previous public datasets utilized for both SFT and preference optimization, such as direct preference optimization with UltraFeedback. This advantage is evident on alignment benchmarks such as AlpacaEval, ArenaHard, and WildBench.

## 摘要
<details><summary>点击展开</summary>
高质量的指令数据对于对齐大语言模型（Large Language Model, LLM）至关重要。尽管诸如Llama-3-Instruct等部分模型已开放权重，但其对齐数据仍处于保密状态，这阻碍了AI的民主化进程。现有开源数据构建方法面临人力成本高昂、提示词预设范围有限等问题，难以实现有效扩展，进而可能限制了公开对齐数据集的多样性与质量。我们能否直接从已对齐的大语言模型中提取数据，从而规模化合成高质量的指令数据？为此，我们提出了一种用于生成大规模对齐数据的自合成方法，命名为Magpie。我们的核心观察在于：得益于自回归特性，当我们仅输入至用户消息预留位置的左侧模板时，诸如Llama-3-Instruct这类已对齐的大语言模型能够生成用户查询。我们利用该方法对Llama-3-Instruct进行提示，生成了400万条指令及其对应的回复。我们对提取得到的数据进行了全面分析，并筛选出30万个高质量样本。为了将Magpie数据集与其他公开指令数据集进行对比，我们分别使用每个数据集对Llama-3-8B-Base进行微调，并评估微调后模型的性能。实验结果表明，在部分任务中，使用Magpie数据集微调得到的模型性能可与官方的Llama-3-8B-Instruct相媲美——尽管后者通过监督微调（Supervised Fine-Tuning, SFT）与后续反馈学习，使用了1000万条数据进行增强。我们还证实，仅使用Magpie数据集进行监督微调，其性能可超越此前同时用于监督微调与偏好优化的公开数据集，例如结合UltraFeedback的直接偏好优化（Direct Preference Optimization, DPO）。这一优势在AlpacaEval、ArenaHard以及WildBench等对齐基准测试中均有体现。
